Weathering of rocks can occur in many ways. In the western United States, strong winds can erode huge rock formations by blowing

stepan [7]

Answer: physical or mechanical weathering

Explanation:

Mechanical weathering which is also referred to as the physical weathering occurs when a rock is broken down into smaller pieces. In this case, there will be a physical change of the rock but its composition will not change.

Some examples include ice freezing and expansion of the cracks in the rock, Smstrong winds that carrycpieces of sand which then sandblast surfaces, moving water which causes abrasion etc.

Find the magnitude of the impulse delivered to a soccer ball when a player kicks it with a force of 1360 N. Assume that the play

Alona [7]

Answer:

7.59Ns

Explanation:

Given parameters:

Force = 1360N

Time of contact = 5.85 x 10⁻³s

Unknown:

Impulse = ?

Solution:

The impulse of the ball is given as:

Impulse = Force x time

Impulse = 1360 x 5.85 x 10⁻³ = 7.59Ns

Sir Percival and his horse are standing still on a field of honor when Sir Rodney, atop his steed gallops by with a constant vel

Ludmilka [50]

Answer:

d. none of these

Explanation:

From the given information:

Let assume that Percival catches Sir Rodney's horse in time "t" after covering a certain distance "s"

Then, using the second equation of motion:

$S = ut + \dfrac{1}{2}at^2$

FOR Percival, we have:

$S = (0\times t ) + \dfrac{1}{2} \times 0.6 \ m/s \times t^2 \\ \\ S = 0.3 \ m/s \times t^2 -- -- (1)$

FOR Sir Rodney;

$S = ut + \dfrac{1}{2}at^2$

$S = (3\times t ) + \dfrac{1}{2} \times 0 \times t^2 \\ \\ S =3t--- (2)$

Equating both equations together; we have:

0.3t² = 3t

0.3t² - 3t = 0

0.3t(t - 10) = 0

If Percival's position at rest = 0

Then; t = 10 s.

Nebular hypothesis.

Explanation:

The first version of the nebula hypothesis was proposed by Immanuel Kant and Pierre Laplace.
Today the hypothesis has been revised to fit into more current and update realities about how our solar system emerged.
The hypothesis is the widely accepted explanation to the origin and evolution of the solar system.
It suggests that the star and the planets that makes up the solar system were products of a huge cloud of dust called the nebular.
The nebular is a huge mass of interstellar dusts.
The cloud collapsed and condensed under gravitational pull of the materials.
A center core that resulted in the formation of our star, sun emerged and the rest of the particles formed our planet.
